SPINNING- MACHINE.

SPECIPICATION forming part of Letters Patent No. 326,900, dated September 22, 1885.

Application filed October 15, 1884. (No model.)

To all whom it may concern.-

Be it known that I, JoI-rN CUTHBERTSON, of Lowell, in the county of Middlesex, of the Commonwealth of Massachusetts, have invented anew and useful Improvementin Spinning-Machines; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a Vertical section of a spinningframe spindle and bobbin provided with my invention, the nature of which is defined in the claims hereinafter presented. Fig. 2 is a side elevation of the spindle with its two catches, such figure also showing the box 0, cup E, spring H, fork F, and bar G, to be described. Fig. 3 is a horizontal section of the bobbin, taken through the catch-recesses in its lower part, such figure also showing a transverse section of the spindle A and the leverlatches B B, to be explained. Fig. 4 is a horizontal section taken through the spring H, Fig. 1, to be described, and showing the fork F, and mechanism for operating it, as explained, the shaft G and supports I being broken away.

My improvement relates to the spindle and bobbin.

In carrying out my said invention I provide the spindle A with two lever-latches, B, pivoted within and projecting, as shown, from a cylindrical box, 0, fixed on the spindle concentrically therewith. The tails or lower arms, a a, of these latches bear against the upper part of a spiral spring, I), arranged within the box and around the part of the spindle which is therein. The latches are to enter a cylindrical chamber, 0, in the base of the bobbin 1), such chamber at two opposite sides of it opening into two notches or recesses, (Z, in the bobbin, and adapted to receive the heads of the latches, and with them to hold the bobbin upon the spindle, the heads being formed or rounded, as shown, in order that the bobbin, when pressed down upon the latches, shall cause them to move toward each other and enter its chamber and catch into the notches opening therein. Each catch-shoulder of the latches stands at an obtuse angle to the arm from which it projects, such being to enable the bobbin on being pulled upward 0n the spindle to be unlatched therefrom. The heads of the latches, when in the recesses (I, enable the spindle to revolve the bobbin.

Below the box 0 there is on thespindle concentrically a cylindrical cup, E, that slides 011 the spindle longitudinally thereof. This cup has an internal diameter equal to or a very little greater than the diameter of the box 0, such being to enable the box, when the cupis pushed up to it, to enter and fit or nearly fit the cup.

A fork, F, projecting from a bar, G, spans the spindle, and is connected to the cup by a spiral spring, H, extending around the spindie. The said bar G constitutes a shaft for supporting the said fork. In practice the bar or shaft G is to be suitably journaled in the spinning-frame, and may be turned in its bearings by an arm or other proper mechanism suitably adapted to it. Instead of such arm or mechanism, a person, by taking hold of the fork F, can with his hand raise such fork upward in order to force the cup E up to the box 0. I11 Fig. 4. the shaft G is shown as journaled in the end portions, I, of the frame of the spinning-machine, and provided with an arm or handle, K, to enable it to be turned in its bearings by the hand of a person applied to such arms.

From the above it will be seen that when the bobbin is latched to the spindle and the latter is in revolution such bobbin will not only be held in connection with the spindle, so as to be prevented from being accidentally thrown upward thereon, but will be revolved b it.

Just previous to doffing the bobbin the yarn extending from it to the delivery-rollers of the spinning-frame is to be carried across the bottom of the box 0, and the cup E is next to be raised or forced upward, so as to pinch the yarn between it and the box. The full bobbin is next to be removed from the spindle and an empty one put thereon. On pulling the full bobbin upward the yarn leading from it to the cup will be broken. Next the spinner is to lower the fork a little, so as to relax the spiral spring. On the yarn being by the faller raised above the head of the bobbin and the machine started up,the yarn will be wound about the empty bobbin and drawn from between the box and cup, after which the latter is to be depressed.

I claim 1. The spindle provided with the box and the latches and their operative spring, as described,in combination with the yarn-clamping cup, (to slide on the spindle and co-operate, as described, with the box in clamping the yarn to the spindle prior to doffing the bobbin,) and with mechanism, substantially as described, for operating the said cup, such mechanism consisting of the spring H, the fork F, and its pivotal shaft G, and the arm K thereof, all being arranged as represented.

2. The combination of the spindle,provided 1 5 with the latches and their operative spring, with the bobbin chambered in its lower part, and having opening out of the chamber notches 0r recesses to receive the heads of the latches in order to engage the bobbin with the 20 MARTIN L.
